The Reedy 540-SL4 is a great upgrade option for your sensorless brushless RTR! Due to its sensorless 4-pole configuration, the 540-SL4 operates powerfully, efficiently, and reliably in a variety of vehicles and ESC applications.

The 3300kV rating provides plenty of speed with 2S LiPo batteries. But install a 3S LiPo battery for insane speeds that are barely controllable! A high-strength rotor provides plenty of torque and resists overheating better than 2-pole alternatives.

Flexible silicone wires ease wire routing in tight spaces and work in conjunction with 3.5mm bullet connectors to reduce power-robbing resistance and heat. Triple insulated windings, a hardened steel shaft, and oversized ball bearings enhance reliability to keep you out of the pits and on the track.
